A lawyer in Ted Cruz’s home state of Texas has filed a lawsuit to challenge the Senator’s status as a “natural-born citizen” and thus his eligibility to run for President.

Republican presidential contender Ted Cruz should be disqualified from the race because he isn’t a “natural-born citizen,” a fellow Texan claims in a “birther” challenge filed against the senator in a U.S. court.

The suit seeks a court definition of the term to clarify whether Cruz — who was born in Canada to an American mother — can or can’t serve if elected.

“This 229-year question has never been pled, presented to or finally decided by or resolved by the U.S. Supreme Court,” Houston attorney Newton B. Schwartz Sr. said in his 28-page complaint. “Only the U.S. Supreme Court can finally decide, determine judicially and settle this issue now.”
